Smart shirts are nothing new. They can capture data as you perform moves to help you stay on the right track. QUS is a smart shirt & bra with intelligent sensors that captures data without a chest strap. You will be able to view heart, respiration date, HRV, calories, sleep, acceleration, and g-force on your smartphone.
You get a bra/shirt, 1 x OBU, and app with your purchase. The OBU is waterproof and has 4 docking buttons, GPS, accelerometer/gyrometer, and Bluetooth. You can find out more about the project here.
